Experiments and Numerical Simulations of Horizontal Two Phase Flow Regimes
Stratified two-phase flow regimes can occur in the main cooling lines of Pressurized Water Reactors, Chemical plants and Oil pipelines. A relevant problem occurring is the development of wavy stratified flows which can lead to slug generation. In the last decade, the stratified flows are increasingly modelled with computational fluid dynamics (CFD) codes. In CFD, closure models are required tha...
متن کاملNumerical Tools for Unsteady Viscous Flow Control
Abstract: This paper reports about progress in the development of numerical tools for adaptive aerodynamic configuration design. We try to illustrate the use of new software components allowing for the parameterized modelling of boundary conditions and the simulation of compressible steady and unsteady viscous flows including a computational flow control model. A coupling of these tools and the...
متن کاملNumerical Methods for Incompressible Viscous Flow
We present an overview of the most common numerical solution strategies for the incompressible Navier–Stokes equations, including fully implicit formulations, artificial compressibility methods, penalty formulations, and operator splitting methods (pressure/velocity correction, projection methods). A unified framework that explains popular operator splitting methods as special cases of a fully ...
متن کاملDirect Numerical Simulations of High Speed Flow over Cavity
Direct numerical simulations are used to investigate the effect of Mach number on the unsteady flow of an open cavity. The implicit solution is obtained for the compressible Navier-Stokes Equations using compact sixth-order spatial differencing coupled with tenth-order implicit filters. Results for transonic and subsonic flow over a two dimensional cavity are presented for the sound pressure le...
متن کاملNumerical simulations of glottal flow
Features of glottal flow are visualized by numerical simulation, using a Navier-Stokes solver for two-dimensional, incompressible flow. Four different shapes of glottal passages are examined, for comparison to stationary model measurements. Results include pressure distributions leading to the forces acting on the vocal folds and illustrate entry pressure loss and exit recovery. Flow field imag...
